Dayot Upamecano has admitted to speaking with other clubs despite being under contract at RB Leipzig.
Manchester United have reportedly stepped up their pursuit of the 21-year-old centre-back, who received his first call-up to the France national team this week.
Arsenal and Real Madrid have also been linked with the centre-back.
And despite being under contract with Leipzig until 2023, Upamecano has admitted he has chatted with other clubs.
"I have extended my contract with Leipzig," Upamecano said.
"I am targeted by several clubs, I speak with clubs, but I have time. We will see what happens in the future."
